Kodi PT100 sensor imagwira ntchito bwanji?

Chithunzi cha PT100ndi sensa yotsutsa kutentha yomwe mfundo yake yogwiritsira ntchito imachokera ku kusintha kwa kukana kwa conductor ndi kutentha.PT100 imapangidwa ndi platinamu yoyera ndipo imakhala yokhazikika komanso yokhazikika, motero imagwiritsidwa ntchito kwambiri poyezera kutentha.Pa zero digiri Celsius, kukana mtengo wa PT100 ndi 100 ohms.Pamene kutentha kumawonjezeka kapena kuchepa, kukana kwake kumawonjezeka kapena kumachepetsa moyenerera.Poyesa kukana kwa PT100, kutentha kwa chilengedwe chake kumatha kuwerengedwa molondola.
Pamene sensa ya PT100 imayenda nthawi zonse, mphamvu yake yotulutsa magetsi imakhala yofanana ndi kusintha kwa kutentha, kotero kutentha kumatha kuyesedwa molakwika poyesa voteji.Njira yoyezera iyi imatchedwa "voltage output type" muyeso wa kutentha.Njira ina yodziwika yoyezera ndi "resistance output type", yomwe imawerengera kutentha poyesa kukana kwa PT100.Mosasamala kanthu za njira yomwe imagwiritsidwa ntchito, PT100 sensor imapereka miyeso yolondola kwambiri ya kutentha ndipo imagwiritsidwa ntchito kwambiri pazigawo zosiyanasiyana za kutentha ndi kuyang'anira ntchito.
Kawirikawiri, sensa ya PT100 imagwiritsa ntchito mfundo ya kukana kwa conductor kusintha ndi kutentha kuti athe kuyeza bwino kutentha poyesa kukana kapena voteji, kupereka zotsatira za kuyeza kwapamwamba kwambiri kwa kutentha kwa kutentha ndi kuyang'anira ntchito zosiyanasiyana.
